Be it' known that we, ADOLPH. G. ltEcK nn, a citizen of the United States, resldlng l I at Oakville, inthe county of Litcheld and State of Connecticut. and HERBERT Canin 'a 'citizenof the UnitedStates, residing at Wvaterbury,

new and useful lmprovement'inPush-Type Flush Receptacles or Electric Installation;

and we dohereby'declare xthe following,

' when takenv in connection with the vaccom-v panying drawings and the characters of ref- Aerence markedthereon, to be afull, clear,

' improved push-type flush receptacle,

` In carryinioutfour invention las herein the rectangular. Areceptaclei, plate 9 is' providtglith aen-cular opening osite points of which two par- 10 from opp llel mountmg-arrns-11are turned inwardin the ycounty of New- Havenand State of Connecticut, have invented a central longiand having .ly at right `angles to theplane of the plate for the reception-between themof a circular insulating-block y12 made of porcelain or an equivalent material, and having its outer`end or face slightly reduced ,in diameter to form a narraw-shoulder within the said 'opening 10. A long pin or screw 14 assing through a transverse hole .14a in the block and through the perforations ofthe `said arms secures the block to'the plate, the two forming a unitary structurehandled as lone piece. Under'the constructiondescribed', the forward end of the block projects through `the plate and is substan' vtially flush withthe outer face thereof, as .shown in Fig. 1. On opposite sides of its center'the block is traversed from front torear by corresponding .parallel service-openings 15 entirely isolated from eachother.

These-openings respectively receive corre-- sponding contact-springs arranged longitudinally therein and each having a' spring` contactv armi 16 and a mountin former having by preference` boss 18, and the latter having an opening 19.

-arm '17, the

These contact-springs are held in Aplace by screws 20 located in suitable counter-sunk holes entering the periphery of the inner end ofthe block and intersecting the respective chambers 15 aforesaid at right angles thereto, the inner ends of these screws passing through the holes 19. in the mounting-arms 17 of the .contact springs and thence vintothreaded openings 21 -in the inwardly-turned arms 22 of-two corresponding terminal-plates 23, set into shallow rea retaining- 13 fitting snugly cesses in the inner -face or end of the block threaded openings 24 for the reception of two binding-screws 25 adjacent to.whic h the plates are formed with upstanding fingers' 26 between which the service wires (not shown) pass, and which prevent the same from fouling asthe binding screws-.are turned. The contact-springs are thus held in place by the screws 2O which also lhold the terminal-plates i place, the

binding-screws being exposed upon the rear end of the face of the block and being-separated from' each other by a radial rib or web 27' made integral therewith.

4 mountably fastened by screws 30 to the lugs of an ordinary' loom-box 3l, shown as located in a recess 32 in a wall 33 to which the hox is secured by brackets 35 or in any approved manner; y Under our improvement, the insulating-block, instead of.being relatively large and installed within the loom-box, is reduced in size and mounted upon and carried by the receptacle-plate, of which it forms a unitary part, so that the insulating-block is installed with the plate and removed with/the same. Moreover, the block, on account of its smallness, gives the maximum amount of room within the loombox for the service-wires which, without overcrowding lthe box, may be made long enough to permit the plate and block to be connected with the wires at a point suiciently away from the wall to afford the greatest convenience.

While 'we have shown our invention as embodied in a fixture of the single type, that is, a liXture conned to the employment of a single push-plug, it is equally'well'adapted, as we would have it understood, to be embodied in fixtures permittingfthe use oi two or more plugs.

We claim:

l. A push-type iiush receptacle for electrie installatiomrhaving a receptacle-plate formed with an opening, two oppositelylocated mounting-arms extending rearward# ly from the edges of the said opening at a right angle 'to the plane of the said plate, an insulating-blockl inserted between the said arms and formed with a transverse hole, and means passing through the said arms and through vthe said hole .for securing the block to the plate in line with the said opening therein.

2. A push-type ilush receptacle for electric installation7 having two oppositely-lo cated, perforated mounting-arms extending rearwardly from the edges of the said opening at a right angle to the plane of the said plate, an insulating-block inserted between the said arms and formed with `a transverse hole registering with 'the perforations there in, and a pin passing through the said arms and hole for securing theblock to the plate in line with the said opening therein.

3.` A push-type flush receptacle for electric installation, having two oppositely-located, perforated mounting-arms extending rearwardly from the edges of the said opening at a right angle to the plane of the said plate, an insulating-block inserted between the said arms and formed at its forward end with a shoulder by which it is adapted to be fitted into the said opening from the rear of the plate, and the said block being also formed with a transverse hole; and means passing 'through the said arms and through the said hole for securing the block to the plate with its shoulder positioned in the said opening therein.

'In testimony whereof, we have signed this l specification in the presence of two subscribing witnesses.
